For the life of me I can't figure out how to use variables I've set in atlocal.in in my macros defined in my *.at files. I think it must be due to my lack of understanding of the m4 language, and maybe more specifically the --language=autotest option of autom4te. For example, here is my atlocal.in: DOING_MPI='@MPI_LIBS@' In my macros I just want to check for whether this variable is set, viz, if test -n "$DOING_MPI" ; then do some stuff fi In particular I'd like to change the command I send to AT_CHECK to execute the test executable. But it appears that somehow regular shell commands are stripped out of the macros. For example, in my local.at I have ================================================================= m4_define([AT_RUN_PROGRAM], [ #run="" #if test -n "$DOING_MPI" ; # run="mpirun -n $2" #fi AS_IF(test -n "$DOING_MPI",[run="mpirun -n $2"],[run=""]) AT_BANNER([executing $run $1 $2]) AT_TESTED([$1]) AT_SETUP([$1]) AT_CHECK([$run $1],0,[ignore],[ignore]) AT_CLEANUP ]) ================================================================= (you can see that I've tried both "if test" commands as well as using "AS_IF." I get the same result) a file test.at with ================================================================= AT_RUN_PROGRAM(test_Cell_Field,2) ================================================================= and I have testsuite.at with ================================================================= AT_INIT([pika_fields]) AT_BANNER([pika fields]) m4_include(local.at) m4_include(test.at) ================================================================= (sorry for all of the files, but I'm trying to set up a system where I can plug in lots of test*.at files with a common local.at. Btw, I am using automake and I have testsuite depending on all of these *.at files and that dependency is working. I.e., when I make changes to one of them my testsuite script gets regenerated.) Here is some output from make check ================================================================= autom4te --language=autotest -I '../../../../src/pika_fields/test' -o testsuite.tmp testsuite.at mv testsuite.tmp testsuite /bin/sh 'testsuite' -d ## -------------------------------------- ## ## pika_fields 0 test suite: pika_fields. ## ## -------------------------------------- ## pika fields executing $run test_Cell_Field 2 1: test_Cell_Field ok ## ------------- ## ## Test results. ## ## ------------- ## 1 test was successful. ================================================================= You can see that $run is being treated as a constant, and my variables are not getting evaluated. I also have gone directly into the testsuite script that is generated and added echo "$DOING_MPI" and verified that that value is being read in properly from atlocal. What is it that I don't understand about how autotest macros should be written? Thanks very much. jgw -- John G.
